Two forms of a novel accordion‐shaped non‐linear optical polymer (NLOP) based on cis ‐ and trans ‐1,2‐diaminocyclohexane and o ‐xylyl linkages were characterized by solution‐ and solid‐state NMR spectroscopy. Model compounds and the monomers for both the cis and trans forms of these polymers were also investigated. The cis form is less rigid than the trans form, as demonstrated by the fluxional behavior of the cis model in the solution state.
